Fatigue
You don’t have to live exhausted.
At Sanctuary Functional Medicine, we recognize that fatigue is more than feeling tired after a long day. It’s waking up unrefreshed, pushing through your afternoons with no reserves, and wondering why no one can give you answers. Fatigue is not laziness and it’s not “just stress.” It’s a signal from your body that something deeper needs attention—and we’re here to uncover what that is.

Understanding the Real Causes of Fatigue
Fatigue Is Rarely Just One Thing
Fatigue typically develops when multiple systems in the body become overworked, imbalanced, or inflamed. This is why quick fixes, stimulants, and basic labs rarely solve the problem. Your body is trying to tell you that something beneath the surface needs support.
Hormone Imbalances
When thyroid, adrenal, or sex hormones shift—even slightly—your energy, mood, weight, temperature regulation, and sleep can all be affected. These hormones act as the body’s communication system, and when the messages become disrupted, the entire body feels the impact.
Chronic Infections and Immune Activation
Hidden infections such as Epstein–Barr virus, tickborne illnesses, chronic sinus infections, or mold-triggered immune responses can keep your immune system in a constant state of high alert. Even if you don’t feel sick, your immune system may be working overtime behind the scenes, draining your energy day after day.
Chronic Inflammation
Inflammation is one of the most common root causes of persistent fatigue. Whether triggered by infections, autoimmune activity, toxins, food reactions, or environmental exposures, chronic inflammation diverts energy away from everyday function and toward constant defense and repair.
Mitochondrial Dysfunction
Your mitochondria are your body’s “energy factories.” When they slow down due to stress, toxins, mold, nutrient deficiencies, viral illness, or inflammation, you experience deep, cellular exhaustion—even if life hasn’t changed on the surface.
Nutrient Deficiencies
Low levels of essential nutrients—such as B vitamins, iron, magnesium, vitamin D, and amino acids—can interrupt your body’s ability to produce adequate energy. Even mild deficiencies can create profound fatigue.
Blood Sugar Imbalances
When blood sugar is unstable, energy becomes unstable. Spikes and crashes throughout the day can leave you feeling irritable, shaky, foggy, or completely drained by late afternoon.
Sleep and Circadian Rhythm Disruptions
You may be sleeping, but not actually reaching the deep, restorative sleep your body needs. Sleep apnea, upper airway resistance, inflammation, and circadian rhythm imbalances can all prevent true recovery, even with eight hours in bed.
Environmental Exposures (Especially Mold)
Mold and chemical exposures can trigger powerful immune, neurological, and inflammatory responses. For many patients, addressing mold toxicity is the key to restoring energy and clarity.
Gut Dysfunction and Poor Absorption
When the gut is inflamed or imbalanced, your body struggles to absorb nutrients and regulate inflammation—two essential components of healthy energy production. Fatigue is often tied directly to gut health.
Chronic Stress and Nervous System Imbalance
When the body lives in fight-or-flight mode, healing becomes nearly impossible. Chronic stress affects hormones, sleep, metabolism, digestion, and immune balance—all of which contribute to persistent fatigue.
How We Evaluate Fatigue
A Comprehensive, Layered Assessment
Because fatigue has many potential causes, we investigate deeply and systematically. Our team goes beyond basic labs to understand what’s happening within your hormones, immune system, mitochondria, gut, detox pathways, metabolic health, and sleep patterns.
Testing may include hormone mapping, inflammation markers, nutrient analysis, mitochondrial function panels, mold/mycotoxin evaluation, advanced gut testing, and sleep and circadian assessments. Every test is chosen based on your story—not a one-size-fits-all approach.
Our Functional Medicine Approach
Personalized Plans for Real, Lasting Energy
Once we understand what’s driving your fatigue, we create a tailored plan that supports your body’s ability to heal and restore energy naturally.
This may involve targeted supplements, hormone balancing, anti-inflammatory nutrition, gut healing protocols, detox support, immune and infection recovery, IV therapy, and nervous system retraining. We meet you where you are and design realistic steps that fit your life.
What Healing Can Look Like
As your body begins to rebalance, energy returns more steadily throughout the day. Brain fog lifts. Sleep becomes restorative. Mood improves. Daily tasks feel manageable again. Eventually, you regain the clarity, strength, and vitality to enjoy the life you’ve been too tired to live.
Healing is not only possible—it’s expected when you address the root causes.
You Don’t Have to Push Through
Fatigue Alone
Chronic exhaustion is not normal, and it is not the rest of your story. There are real reasons behind your fatigue, and real solutions that can help you recover.
If you’re ready for answers, clarity, and a path forward, our team is here to guide you every step of the way.
